TS419IST

TS419IST is a 360mW mono audio amplifier with active high standby mode. This monaural audio power amplifier drives in BTL mode a 16 or 32-ohm earpiece or receiver speaker. The main advantage of this configuration is to get rid of bulky output capacitors. Capable of descending to low voltages, it delivers up to 220mW per channel (into 16 ohm loads) of continuous average power with 0.2% THD+N in the audio bandwidth from a 5V power supply. An externally controlled standby mode reduces the supply current to 10nA typical. It can be configured by external gain-setting resistors. It is used in applications such as 16 / 32ohm earpiece or receiver speaker driver, mobile and cordless phones (analogue / digital), PDAs & computers, portable appliances.
